Today, glue guns are widely used in everyday life and in production. They are used by makers and builders, home masters and professionals. Makers of the whole world use glue guns for gluing various surfaces (textiles, paper, plastic, wood, etc.). The glue gun is indispensable in many types of creativity and needlework (quilling, scrapbooking, floristry, decoration, etc.).
I often use the glue gun in my work. And I have wanted to have a glue gun, which will produce a drop of glue and dosage will be easier to use, such as a 3d pen.
I created a model of a glue pen with an electric extruder. I took the heater out of the ordinary glue gun. The body and all the mechanical parts are created in Fusion 360. After that, I printed all the details on the 3d printer.

Step 1: List of Components
Body (2 parts)
Stand for glue pen
Electronic and mechanical components:
30RPM Mini DC Metal Gear Motor
Charger module LI-CHARGER-MicroUSB
8 Screws: Self-tapping screws M3X10
2 Hexagon socket head cap screws M3X16
Step 2: 3d Printing
Print all 3D print components
I attach the STL files
NB! Do not use PLA plastics, as it can deform when heated
Step 3: Electric Parts Assembly
Connect the charger module to the battery
Connect it to the micro-adapter
The capacity of this battery ensures continuous operation for 1 hour
If the glue pen should work for a longer time, it will be better to use a more powerful external battery.
Step 4: Button Holder
Put the button in the holder
Solder the wire length of 10 cm
Glue the button holder to the case at the level of the U-hole
Step 5: Motor Part Assembly
Assemble the motor part
Screw rollers and motor
Fix the motor part to the body with screws
Step 6: Extruder Assembly
Place the charger module with battery
One button wire connect to the motor
The second wire of the button is soldered to the board
The second motor wire is soldered to the board
Press the button and check the direction of the feed roller
Step 7: Final Assembly
Insert the heating part
Collect the body completely with screws
Step 8: Go to Work!
Connect the glue stick to the mains
Wait when warmed up and get to work
I tested a glue gun when assembling a kitchen set - a bowl and a napkin
GlueDart works with 11 mm glue rods
I want to create a glue pen for 7 mm rods and 12-volt power.
